The hars3l an d'fingers33 constitute the lipper and forward gates, "depend .ing on; the position ofthe sho clrforrn'er,

While the bars 32 Mid fingers 3 4" constitute the bottomandrear gates,depending. on

theposition of the shock former, and ina'se much as each bar20'carries'a pair of; gates, the forward or upper and .the'bottom orrear gates are alternately disposed i spanning relation with-the talole"3.. The" gates are all yieldingly, impelled toward open p'os-itions bysprings 35 transversely spanning the bars 20 and having terminalconnections with lateral pins on theibars andi32l' The. actuating meansfor the shock "forme -r which is shifted from the horizjontalte the vertical po'sition and viceiversa consists oi V a crank shaft 36 journaledin the standards 19 and havi'n cranks 37 connected with the a side bars20 y'connect'ing rods 38 In the normal horizontal positlon of the shockformer, the side bars 20 are ho rizontal and in such position. thecranks 37 and connectingrods 38 are also horizontal. In such a position,the springs '318 free to move the upper or forward gates to openposition but the bottom or rear gates are retained in closed positionbecause of the extensions 39 on the-connecting rods overlapping thebars32. Thus, the bundles of grain transferred from the conveyor l may bedeposited in the shock former, the fingers 34 constituting the bottom ofthe shock formerin' the horizontal part of the present invention, nosuch coni in struction is disclosed, being unnecessary to anunderstanding vof the invention;

Afterthe shock has been tied, the shock former isfactuated by the crankshaft 36 ut in motion. Theflower ends of the rar s 20 then traver'se'the-side bars or rails 23 of the shock table and the shock former movesfrom a horizontalto a vertical position, during which operation the con:nectingrods assume angular positions with reference tothe side bars 20and in'so doing thebars 3I,-rocking them'on their 1 orrear gates to openpivots and moving the forward' or u per gates to; closed position;"sWhen the s ock former has reached a vertical position, -hpwever, theprojections 39 will have 'assed Out of obstructing relation with'the si'e bars 20 (as clearly-shown in Figure 4')and the springs 35 will-be freeto move the bottom sition "so that the shock'may be discharged.

"Daring this eriod of movement o'fzthe' shock former-,1: "e tableS'isdesigned to'be held statinnary it being mounted for oscillatingmovement on the axle 5' to which it is connected by means of straps .40"secured some under surface ofthelside rails'23 aniifthe bottom of thetable consists'of fin- $1; supported by transverse. bars 42 y spanningthe sidefrails. When the shock V struction provides forthe release ofthe table reaches vertical'position, the: consothat the rear endmay dropto permit the terminals of. the fingers 41 to rest upon the ground, sothat as thefrear gates open the shock may be readily deposited.

The means for locking the table to prevent oscillatory -movementconsists of a latch memb'er43having a nose 44 engaging afba'r 45spanning the side rails 23 and a spring .46 functions to impel thelatch' meinber toward the bar for the engagement of thenose 44therewith. The latch member is. designed for actuation by a cam 47carried on the crankshaft and thiscam engages an extension 48 on thelatchmember and in the vertical position of the shock former. The riseof the cam engages the extension and thus deflects the latch member soas to disengage the'nose 44 from the bar 45, thus permitting the rearend of the table to drop and the shock former having an interlockingengagement with the shock table through the instrumentality of therollers 25' and 26 also lowers with the table, the pivotal connec tionsof the connectingrods 38"and the tie shock has been discharged, theshock former vis returned quickly to its receiving hori zontalp0sition,"and to this quick return forthecrank shaft is-p'rovided iiitheform of a spring 49 tensioned between a lateral post 50 on'the frame4and a crank arm51 on one extremity of the crankshaft. The connectionbetween the drivinglmeans and the crank shaft is such as to permit this,as hereinafter appears'fAfter the; crank shaft has begunits second halfof the revolution which returns. the shock former: to horizontalposition,the spring49 begins tofunction and the quick return isaccomplished, the bars 20, after the inner-ends have passed the axle 5,serving to depress the-'reare'nd of the table until finally the-nose 4Ais en gaged with the bar or rod .45 and the table is latchedin'position. i "The sprocket 12 constitutes the driving means forthe'crank shaft 36 forgthe first half of its revolution when theshock formeris shifted to vertical'position. It isaxiallyaligned with the crank'shaft-sncejthe stub shaft 16 isan extension of the latter,'fland {theoperative connection between, the sprocket opposite V lugs 52*latera'llyprojecting from theisprocket and'engageablewith a pivotal arm 53 carriedby the crankshaft and have force communicated tothe crank shaft. Solong'a's the spring i9 remainsinert, as whenthe shock former istraversing to verticalposition, the arm 53 remains in engagement with"one of the lugs 52 but mmediately the spring begins to functiom'thecr'ank shaft is carried quickly in the direction inwhich it inn 7,

and the crank shaft constitutes diametrically the lugs I wasspreviouslymoving and the; arm 53' is thereby carried away'from thelug and con-'tinues-l its travel around-the flange of the head 55 untilit reachesa'position opposite the notch 56,\into which-it is forced by acompression spring 57; carried on the stub shaft 16. Thestub, shaft 16maybe made an integral part of the crank sliaft 36,-or may be. separate!therefrom, or separate and couple'd theretm as practice may dictate.

So long as the arm 53 remains in engagement WltllthG notch 56, the crankshaft 36 remains inactive. and the'shock former rests in its normalhorizontal receiving position.

Whenit is desired that the shock former,

: shall shift to its-discharging'positiomthe operatorshifts theilever.58 which'is pivot ally mounted, as at 59, on one of the'standands, 19adjacent the head 55 and this lever being disposedin obstructingrelation with j the extremity of the arm 53 projecting radially beyondthehead, the arm 53 is shifted out-ofthe notch 56 against the pressureof the spring 57 and disposed for engagement wit-hone of the lugs 52when motion will be communicated to the crank shaft andactull ation ofthe shock former and table effected asbefore described. -Motion isobviouslyv r carried on a shaft 63 mounted in the looped,

bracket l8, The bevel gear 62 is in mesh with abevel gear6 ilooselymounted on the drive shaft 65of the conveyor and is. operativelyconnected therewith through a clutch ofwhichithe spring actuatedelement66 is yiel'dingly impelled toward the gear-carried element 67. When theshock former is being actuated; to dischargeyits load, it is essentialthat the conveyor be stopped and to this end a cam member 68 is mountedon the crank shaft 86 and engages ajshifter lever 69 pivoted on theupright 19 as at 70. When the shock former is in its receiving position;the

crank shaft is at rest, and the flat edge 68 on the cam member 68 ispositioned opposite the shifter leverflthus permitting the spring toforce the clutch member 66 into engagementwith the clutch member 67 Whenthe, shock former is actuated by motion communicated to the crankshaft36, the cam 68 is also actuated and oscillatory movement communicated tothe shifter lever, thus sepa rating the clutch members 66 and 67 andleaving the conveyor inoperative.
